Question

Leon counts the number of bugs he finds on his tomato plants each day and collects the following data: 18, 24, 15, 9, 10. The mean is 15.2. What is the final equation that he would use in determining the mean absolute deviation? Round each value to the nearest tenth.(2 points)

Answer 1

The equation to determine the mean absolute deviation (MAD) is:

MAD = (|data point 1 - mean| + |data point 2 - mean| + |data point 3 - mean| + ... + |data point n - mean|) / n

Using the given data points and mean, the equation would be:

MAD = (|18 - 15.2| + |24 - 15.2| + |15 - 15.2| + |9 - 15.2| + |10 - 15.2|) / 5
